The leaf area index can be used to reflect the growth status of crops. The changes reflect the different status of vegetation growth and development, and are closely related to the photosynthesis of crops, crop evaporation, evapotranspiration and other processes. It is a key for crop monitoring, yield estimation and disease evaluation. The ecological parameters. Accurate measurement of LAI is of great significance. The formula for the conversion of leaf area index is: leaf area index = leaf area/land area, so measurement of leaf area is a key factor in this measurement process. The leaf area can be determined using a portable leaf area meter for rapid determination. There are certain reasons why this method is used for the determination.
The traditional methods of measurement are mostly measured in vitro, and damage the blades to a certain extent, and the process is time-consuming and the equipment is generally expensive. In recent years, some scholars have also carried out a lot of research on leaf area non-destructive testing. However, most of these studies use image processing software to perform measurements, involve more complicated processing steps, and are not conducive to the promotion and application of measurement methods. Therefore, the time-saving, convenient, accurate, and non-destructive leaf area determination method is more in line with the needs of future research work. At the same time, a large number of studies have proved that leaf length, leaf width, leaf weight and petiole length are all significantly related to the leaf area, which provides the possibility for the non-destructive determination of leaf area. Through the model fitting, a non-destructive method for leaf area determination suitable for field measurements can be established. Continuous measurement of the same leaf can be achieved, and the dynamics of leaf growth, development, etc. can be studied, especially for plants with low plant density. This measurement method uses both the regression equation method to measure the leaf area of ​​the plant. The main difficulty of this method lies in the calculation of the regression equation of the plant. The Sino-German relationship needs to be analyzed through dozens of sets of data. Complicated trouble. In order to measure the leaf area of ​​plants more easily and quickly, after continuous research and updating, a portable leaf area meter was developed to perform accurate and rapid measurement of the leaf area of ​​the plant.
Therefore, measuring the leaf area of ​​a plant is a key factor in measuring the leaf area index, and it is relatively accurate to use the leaf area detector to measure the leaf area.
